ورق پی وی سی پلاستیکی سفت و سختمعمولاً از روی هم قرار دادن و حرارت دادن ورق PVC نورد شده ساخته می شود. ورق پی وی سی سخت جامد به 3 مرحله گرمایش، 1 مرحله تنظیم و 1 مرحله خنک کننده تقسیم می شود.
1. مرحله گرمایش با دمای پایین
2. مرحله گرمایش با دمای متوسط
3. مرحله گرمایش با دمای بالا
4. مرحله تنظیم گرمایش را متوقف کنید
5. مرحله خنک کننده
PVC rigid board is usually made by superposing and heating the rolled PVC sheet. According to needs, this solid rigid plastic PVC sheet can be flexibly made into various thicknesses. As PVC is a thermally unstable resin, it will decompose to release HCl and form a polyene structure. If processed at high temperature for a long time, it will seriously affect the performance of the product. However, PVC is also a poor heat conductor and slow heat transfer. To prepare products with good performance, the heating time is difficult to control. If the heating time is not enough, the inside of the board is easy to layer; if the heating time is too long, it will not only reduce the production efficiency, What's more serious is that PVC will decompose rapidly at high temperature for a long time, which will affect the performance of the product.
